BRICKMAKING-MACHINE.

To all whom 'it may concern.'

Be it known that I, FRANK a citizen of the United States, Porter,

W. BRrsoN, residing at in the county of Porter and State lof Indiana, have invented certain new and roughening and ornamenting the surface of a brick during the process of making the Same.

One of the objects ofthe' present invenltion is to provide a simple Vand practical machine of the above character which will be cheap to manufacture and install. A. further object is to provide a reliable and eficient machine of the above character which will give an artistic and Toughened nish to the exposed surface of the brick when placed in position in a wall. Other objects will be in part obvious and in part hereinafter pointed out. j Y

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the device hereinafter described, and the scope ofthe application of-which will be indicated in the following claims. V

In the accompanying drawing wherein is shown one of the various possible embodiments of the present invention there is shown in perspective such parts of a complete machine as are necessary to fully understand the present invention. j

Referring to the drawing in detail 5 designates a horizontally disposed frame carrying at its opposite ends rollers 6 around which passes an endless belt 7. This belt is supported between the main rollers by a plurality of smaller rollers 8 mountedin the frame and transversely disposed with respect to the path of travel of the belt. This frame is adapted to be positioned adjacent a die outlet 10 through which a clay stream 11 passes. This stream is forcedv out in any desired manner as by means ofscrew force feed, and a disclosure thereof is believed to be unnecessary to: those skilled in thelart.

At the opposite end of the belt ordconveyer4 Specication of Letters Patent.

f is positioned a cutting means (not shown) l of any desired type, adapted' to cut the clay stream into bricks of proper size.

Above the conveyer is mounted an auX- iliary frame 12 carrving at one side a transversely disposed shaft, on the end of which is keyed a driving pulley 13 connected by means of a belt 14C with any suitable source of power. Adjacent the driving pulley is a sprocket wheel 15 or other suitable form of power conveying `means about which a sprocket chain 16 passes to a second sprocket Wheel 17 mounted on a transversely disposed shaft 18 at the opposite end of the auxiliaryv frame 12. Intermediate the end shafts is a third shaft 20 upon which a wooden roller 21 is mounted, having a polished steel surface 22. This rolleris adapted to be lubricated by means of waste or the like contained in a trough 23 positioned thereabove` The transverse shaft 18 at the right of the frame is provided with a roller 24 having a plurality of projecting pins 25 or the like adapted to scratch or mark the upper surface ofthe clay stream as it passes thereunder. It will also be noted that this transverse shaft carries a smaller sprocket wheel 26 which may .be geared with the driving sprocket wheel 15 when moved to the opposite end of the transverse driving shaft, in order to vary the speed at which the marking roller is rotated.

To the right of the marking device is positioned a second frame 30 pivotally mounted on the upright 31 at each side of the clay stream. 'This frame carries a roller 82 having a sheep skin surface adapted to rest upon the clay stream with any desired degree of pressure and smooth out projections on the roughened upper surface of the clay stream. The pressure with which this roller acts may be varied by means of weights 33 positioned in a trough formed by the fork ends of the uprights carrying this roller. The inclined side of the pressure roller frame forms a screen 34 adapted to catch the small particles of clay that are thrown 0E bythe centrifugal action of the roughening marker roller 24. These particlesfall back on the upper surface of the clay stream and are pressed downwardly as the clay stream passes under the pressure roller 32.

While the operation and method of use of this device should be obvious from the above disclosure, a brief' statement thereof is asA follows: 4

Assuming the clay stream 11 to be forced out through the die 10 on to the conveyer belt 7 it passes under thev lubricated polishing or leveling roller 2l which has previously been adjusted in trunnions 36 at each end to bear with any desired pressure upon the upper surface of the clay stream. The clay stream then asses under the marking roller which is driven counterclockwise at a relatively high speed, that is, much faster than the flow of. the clay stream, so that scratches or indentations are made in the upper surface. The smallfparticles of clay removed by the pegs or pins 25 are thrown up on thel inclined screen by the centrifugal action of the rotating roller 24, from which they fall back onto the upper surface of the clay stream-and are pressed into the rou hened surface by means of the pressure ro er 32 at the right. The clay stream is then cut into bricks ofthe desired size and shape by mechanism not shown.

It is thus seen that the present device provides a simple and practical mechanism for finishing or roughening the exposed surfaces of bricks during their manufacture. The device is automatic in its operation andreliable and efficient in use, and accomplishes among others all of the objects and advantages above set forth. l

As many changes could be made in the above construction and many apparently widely dierent embodiments of my invention could be made, without departing from the scope thereof, I intend-that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and only limited by the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
